The world's population can be projected using the following exponential growth model.

N= Noekt
N = future value
Np= present value
k = rate of increase
t = number of years over which growth is to be measured

At the start of the year 2022, the world's population will be
around 7.95 billion. The current growth rate is 1.08%.

Part A: What is the world's population expected
to be in 2029?

A. 10.87 billion
B. 16.93 billion
C. 8.66 billion
D. 8.57 billion

Part B: Rewrite the initial equation to solve for t.
Α.) t=ln( Nk/No)
B.) t=k ln( N/No)
C.) t=ln( N/Nok )
D.) t= ln( N/No)/k

Part C: In what year would you expect the world's population to exceed 9 billion?
A.) 2026
B.) 2023
C.) 2033
D.) 2029
